## What is RUN interval?

Easily set up and record your Interval and Fartlek running sessions. With the flexibility of using time and/or distance as interval targets for your "Hard", "Easy" and "Rest" efforts. The simple but highly configurable interface on your phone and watch will have you running sooner.

Now with a Distance Goal option for your session. Along with great audio and visual feedback, detailed post-run summary, share your runs to Strava, and a full-featured Apple Watch app.

You can also record your regular runs with voice-over calling out distance and pace feedback.

Key Features:
• Easily create flexible custom interval sessions.
• Utilize three effort targets "Hard", "Easy" and "Rest" in each set, targeting time or distance (meters or miles).
• You can "Skip" any of the three efforts to create flexible sets, like building a progressive intervals session.
• NEW: Set a Distance Goal for your session, that repeats the sets from the start until the distance has been reached.
• Set a Warm-Up and Warm-Down timer or distance around your session.
• Clear and easily glanceable visuals and audio prompts, including vibrations.
• Voice-over prompts to save you from looking at the screen, great for iPhone or headphone users.
• Voice-over prompts include the upcoming intervals effort and time/distance amount, and your last intervals average pace and heart rate.
• Full-featured Apple Watch App!
• Heart Rate Zones! (see description below)
• Indoor Mode, no GPS, for treadmill running.
• Sound Mode, for normal, discrete or silent audio prompts on your watch.
• Vibration feedback on both the phone and watch.
• Detailed run summary, showing pace for hard and easy efforts.
• The run summary also includes interval breakdown, distance breakdown and heart rate details.
• Play music or podcasts while running and still hear the audio prompts.
• Sharing. Share a summary photo with your friends.
• Private data. We don’t send any of your data to a server or share it with anyone.

Session Types:
• Normal Run – Record a normal run, long or short.
• Record Intervals – If you run with a group or do an undefined session, then use the Record Interval option. It allows you to manually change between "Hard" and "Easy" reps, allowing you to record your session.
• Custom Intervals – Our fully flexible intervals that allow you to use time and/or distance for the efforts. Add multiple intervals sets together to create the session you want.

Sharing:
From the summary screen, you can share your runs with friends or across social media. If you want to share directly with friends or across other social media, you can share a summary image with the details of your run.

Heart Rate Zones: (Apple Watch Only)
Zones are displayed as grouped percentages of your maximum heart rate. Giving you an indication of your current work rate based on your current heart rate. Just enter your maximum workout heart rate into our Settings screen and they will display on your Watch the next time you run.
Zone 1: Very Light Effort 50-60% (Gray)
Zone 2: Light Effort 60-70% (Blue)
Zone 3: Moderate Effort 70-80% (Green)
Zone 4: Hard Effort 80-90% (Yellow)
Zone 5: Maximum Effort 90-100% (Red)

Privacy:
We don’t want to know where you have run, that's for you to worry about. We don’t send any of your data to a server or share it with anyone you don't want too. We keep your running records safe in Apple Health so you have control. Apple Heath gives you the control over who accesses your data. We only write and read the data we record from your running.

Feedback:

### 1/5 — Poor customer support

*2026-06-22, version 6.1*

Wow your customer service folks have a bit of an attitude about them. Time to stop using the app.

### 5/5 — LOVE

*2026-05-30, version 5.7*

Great functionality and excellent price. Reliable app, easy to use.

### 2/5 — Great customizable features if you don’t need to listen to any other audio source while you run

*2026-04-25, version 5.7*

Major flaw is not being able to listen to any audio sources while you run. You won’t get any notifications of interval changes, either haptic or audio notifications.

### 5/5 — Love this app!

*2026-04-02*

This turned out to be just what I was looking for. I can customize it or use the suggested intervals. It was super cheap for the paid version and it was totally worth it because they aren’t trying to charge you a monthly fee to keep using the app, which I thought was pretty sweet!

### 5/5 — Amazing App!!!

*2025-12-22, version 5.7*

Very straightforward to use and provides really helpful data for workout.

### 4/5 — Tolle App

*2025-11-03*

Ich habe lange Zeit nach einer App gesucht, die mir ohne Ballast und unnötige Funktionen ermöglicht. Gefunden :-) wenn die Entwickler jetzt noch eine Integration mit Apple Kurzbefehle einbauen, bin ich wunschlos

### 5/5 — Simple, functional and glitch free.

*2025-10-25*

Easy to use app that is perfect for customising your intervals to suit your plan, or a push of the button records a long run. Syncs with the Apple Watch and doesn’t se to get glitches. Have been using this for years and love it.

### 1/5 — it doesn’t let me upload my runs to strava

*2025-09-02, version 5.7*

### 1/5 — Pas content

*2025-08-07*

Ne calcule pas Km fait

### 3/5 — Timer is fine..

*2025-07-15, version 5.5*
